Restful_authentication sending email on each login

Hi All,

I'm facing a strange problem. I've configured RA with default account
activation email setting. All works fine but whenever user logs in, an
email is sent saying your account is activated. This happens on each
login. Can somebody help me out with this? I'm using ruby 1.8.7 and
rails 2.3.8. TIA.
